The job of any range topper for REL is to deliver more of everything, particularly output and dynamics. The 9x is no different in this regard, as it delivers the goods in both music and theatre applications. 9x, however, delivers a level of intimacy, clarity and speed that means there are no longer trade-offs between the sonic balance of smaller models weighed against the power and scale of a model 9.
The all new 9x has even greater output than before, but the headline news is the way it sacrifices nothing in clarity and transparency to achieve this. At this price it opens the pathway for owners of high-performance European floor and stand mounted monitors and smaller panel speakers to enjoy truly full range sound.

Many don’t realize the intense linkage between performance and design here at REL. Performance is everything to us and so it drives physical design revisions. Our engineers, recognizing the need for greater acoustic volume to achieve the goals of greater fluidity and power, turn to the designer who works dimensions to fool the eye into seeing a smaller, more compact footprint even though cabinet volume increases. Using gently rounded corner radii that allows the eye to flow over and see less visual mass. The result is both modern and familiar with no unnecessary adornment.
To achieve higher output with better control requires a complete overhaul of the suspension components. Much like the suspension on a sports car, these items are responsible for the tuning and feel of our designs. By increasing the cabinet volume, efficiency is improved yielding higher output for no more amplifier power. Less back pressure inside the cabinet means we can tune for a stiffer, better controlled driver suspension. We retained the best aspects of our previous design, such as the aluminum center cap responsible for stiffening the lightweight 10” (250mm) cone while adding almost no mass. The updated combination produces considerably better attack and dynamics with greater transparency.
We have retained our signature Class A/B amplifiers used in every generation of Serie T since 2006. Reliability is the key to happy ownership and with some 200,000 and counting of this range leading long happy lives, Serie T/x owners can feel certain of REL’s standard setting reliability. The powerful 300 watt mosfet amplifier used in the T/9x remains an icon with huge reserves of current, massive power supplies but small upgrades are found everywhere. New driver mosfets that open up performance and transparency and new methods for securing the toroidal transformers mean better performance and superior strength.
REL’s legendary High Level Input connection and fast filters are a significant part of the REL story. Connecting via the speaker outputs of your amplifier without drawing any power from it may seem like magic, but the real magic lies in the way the sound takes on a natural character. Unique tuning and special limiters mean the T/x range sounds fresher, faster and more dynamic than before.
Standby Mode switch is only included on 220V units.
At REL, we’ve developed a sterling reputation for building the finest sounding, fastest wireless systems available in the industry. We never rely upon digital compression as it results in dull, lifeless sound. Instead, we have perfected an (optional) Arrow™ wireless system so fast and dynamic we’re comfortable encouraging the use of wireless on one channel of a pair of RELs while the other channel may be connected conventionally with cable.
The T/9x delivers fast, musical bass along with deep, powerful low frequencies that elevate both music and home theater systems. It’s an outstanding all-around subwoofer, adding texture and clarity to your system. To achieve this performance, we’ve implemented a 10" active driver, a 10" passive radiator, and a 300-watt Class A/B amplifier—all housed in a compact, high-gloss enclosure designed to complement premium audio setups.
The T/9x delivers fast, natural bass with depth and authority. For music, it enhances texture, timing, and soundstage; for home theater, it adds weight and realism to every scene—all while maintaining the speed and clarity that define REL’s musical approach to low bass.
Yes, the T/9x can be integrated with other REL models. This comes in handy when building a REL 3D set up where you can mix and match different models and pair them with different sets of speakers in your theater set ups. For stereo pairs, two of the same model is required to achieve the stereo effect. In theater setups, it works beautifully alongside other series—such as Serie HT or Serie S- to improve impact, clarity, and balance for realism that is sure to make you smile.
Yes, the T/9x is fully compatible with our Arrow Wireless System, which includes all the same input options found on the rear amplifier panel. Arrow delivers high-performance wireless connectivity with zero compression and ultra-low latency—ideal for clean, cable-free installations or setups where the subwoofer is positioned farther from your main system.
The T/9x performs best in medium to large rooms, typically between 150 and 400 square feet. Its combination of driver size and amplifier power delivers rich, room-filling bass while maintaining the speed and clarity REL is known for—whether in a 2-channel music system or a home theater setup.
No, the T/9x is not designed for vertical line array stacking, and we strongly advise against attempting it. However, it excels in stereo pair configurations for music and in REL 3D setups. For vertical stacking applications, we recommend stepping up to the HT/1510 Predator or our Serie S subwoofers.
